Serious contamination of weather radar data can occur in atmospheric conditions that cause anomalous propagation of the radar beam. Excessive downward refraction of the beam may be sufficient to cause ground returns (“anaprop”), which may be diff

The use of a simple conceptual model depicting the life cycle of a convective cell, including the production of daughter cells, has been examined as a way of improving nowcasts in certain showery situations. The evolution of the cell from birth throu

Fluoroscopic procedures, in general, result in much higher exposures to patients than do most types of radiographic procedures [National Council on Radiation Protection, Report 100, p. 31 (1989)]. In spite of this, fluoroscopic exposure rates can var
